Shahnawaz 6 months back charged me 15 k for an oil change but i got 8 litres of oil from them even though my car takes 5.8-6 litres as i use the spare oil in my other cars as well. The 15k cost included 8 litres of oil, oil filter MB genuine and labour
A copper crush washer is simply a washer on the drain bolt just like any car would have a washer on the drain bolt but its made out of copper and crushes when you tighten it, its supposed to be either changed everytime the bolt is opened or resued by heating the washer till its red hot and then dunking it into water, it will necome soft and aneealed and can e reused then. This ensures no leaks ever.
Shahnawaz did not have to change the crush washer as they always do oil change from top
Meaning that they suck all the oil out using the machine and oil filter is on top too so there is no need to go underneath the car nor open the drain plug
They took about 20 min
Btw the oil filter itself also comes with a o ring in the box and that must be changed at every oil change also, and that was obviosuly changed by them.
Also they were the only ones in lahore at that time that had the recently updated mobil 1 packaging with only 2 month old manfucaturing date of oil whereas even the official mobil 1 dealer in lahore was using old packaging with 1.5 year old manfucaturing dates at that time.
While at it they also did a general inspection of the car without charging anything and they uncovered no problems with the car although a year back they had done a complete inspection anyway.
And they also reset the FSS counter so that the car would remind me for my next change.
Oh and all this time i stayed with the car in the workshop and observed the interacted with the techincians doing the work on my car instead of just sitting in the waiting lounge so i was satisfied with their work.
